This is another option if you would ever want to handle them separately.

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="person")
 * @ORM\HasLifecycleCallbacks
 */
class Person
{
    ..........

    /**
     * @var datetime $created
     *
     * @ORM\Column(type="datetime")
     */
    protected $created;

    /**
     * @var datetime $updated
     * 
     * @ORM\Column(type="datetime", nullable = true)
     */
    protected $updated;


    /**
     * Gets triggered only on insert

     * @ORM\PrePersist
     */
    public function onPrePersist()
    {
        $this->created = new \DateTime("now");
    }

    /**
     * Gets triggered every time on update

     * @ORM\PreUpdate
     */
    public function onPreUpdate()
    {
        $this->updated = new \DateTime("now");
    }

    ..........
}
